I think I am 5/20. Got them all from 2 weeks of LFR Pinnacle of Storm (or whatever the name for the last part of the LFR is). I don't have alot of time on my hands lately, so my lucky streak was most welcome, I did run another LFR wing this week (halls of flesh) but got none.

Got my cloak this lockout. Quest bugged the first time and I wasn't able to turn it in, so I had to drop it and redo the whole quest over again. The solo challenge felt nice and fun though - a refreshing change of pace from the usual "Collect this many of ___________" that the Legendary questchain usually is about.

7/12 only got a runestone from Lei Shen this week unless i manage to down some of the bosses that drop runestones on normal mode.

If you have already killed the LFR versions, the normal mode or heroic mode will NOT drop any for you. You get 1 chance per week and however you decide to use that chance is your choice (LFR, Norm, Heroic).
